计算机辅助设计是近十余年来才在孔型设计方面得到应用的。目前,由于孔型设计的理论尚不完善,计算机孔型辅助设计技术也处在需要进一步完善和深化的阶段之中。下面简述各国的发展概况。在美国钢铁协会的主持下。Battelle-Columbus 实验室和 Timken 公司联合研制发展了一个名为 RPDROD 的计算机圆钢孔 Computer-aided design is applied in the hole design for more than ten years. At present, due to the imperfect theory of hole design, the computer assistant design technique is also in the stage of further improvement and deepening. The following brief overview of the development of various countries. Under the auspices of the American Iron and Steel Institute. Battelle-Columbus Laboratory and Timken jointly developed a computer called RPDROD round hole
